Definitions

  • This invention relates to an optical device according to the preamble of claim 1, which is designed such that the relative angle of two plates comprising transparent optical elements having an optically transparent substance enclosed therein is varied to thereby arbitrarily vary the optical performance of a light beam passed therethrough, and this optical device is suitable for an image stabilizing optical system disposed, for example, in a portion of the photo-taking system of a photographic camera, a video camera or the like and designed to correct the vibration of an image caused by the vibration of the photo-taking system.
  • an optical device proposed in JP-A-41-11906 is comprised of two transparent plane parallel plates disposed in opposed relationship with each other, a connection member in the form of flexible bellows surrounding the plane parallel plates, and transparent liquid enclosed therein.
  • Figure 6 of the accompanying drawings is a schematic view of an optical device proposed in JP-A-2-124518.
  • optically transparent plane parallel plates 1 and 1' formed of glass or a plastic material or the like have their circumferences held by annular support members 4 and 4' comprising plastic molded articles or the like of high hardness.
  • a cylindrical connection member 2 formed of laminated high molecular film, aluminum foil or the like and formed into a Y-shaped cross-section is made by the tip end portions of two deformable members being thermally secured to each other and has its other ends thermally secured to the support members 4 and 4'.
  • An optically transparent substance 3 comprising water, alcohol, glycol, silicone oil, silicone gel, silicone rubber, organic oil or the like is enclosed in a space defined by the support members 4, 4', the plane parallel plates 1, 1' and the connection member 2.
  • the angle of the two plane parallel plates is varied to thereby form a variable angle prism whose vertical angle is arbitrarily controllable, and an incident light beam is deflected by a predetermined angle and caused to emerge.
  • the optical device of the above-mentioned JP-A-2-124518 comprises the arrangement of the connection member 2, the support members 4, 4', the plane parallel plates 1, 1' and the transparent substance 3 and therefore, it has suffered from the undesirable possibility that when it is brought into special environment and the internal pressure of the optical device rises, the volume of the transparent substance 3 within the optical device expands and thus, the plane parallel plates 1, 1' are forced out by the internal pressure and slip off.
  • a generic optical device is known from the JEE Journal of Electronic Engineering, vol. 29, No. 306, 1 June 1992, Tokyo, pp84-85. According to this reference, the optical device is capable of varying the direction of a light beam and comprises a pair of transparent optical elements which are arranged spaced apart from each other to define a space therebetween which is filled by a transparent substance.
  • a pair of support members supports the optical elements such that each support member partly covers a portion of the outside surfaces of the optical elements.
  • a deformable connection member is adhesively secured to the support members and allows the angle between the optical elements to be varied.
  • two transparent optical elements are disposed in opposed relationship with each other and they are connected together by a connection member so as to define a space therebetween and a transparent substance enclosed in the space is sandwiched to form a variable angle prism, the air-contacting surfaces of the optical elements are held by support members, whereby the optical elements can be prevented from slipping off the support members.
  • planar optical elements are held by support members in a manner similar to the aforedescribed manner and further, a connection member is adhesively secured to the planar optical elements, whereby there is obtained the effect of enhancing internal airtightness.
  • planar optical elements are held by support members in a manner similar to the aforedescribed manner and a connection member is adhesively secured to the planar optical elements and further, the connection member is thermally secured to the support members, whereby there is obtained the effect of enhancing internal airtightness as well as enhancing the adhesive securement strength of each portion.
  • Figure 1 is a cross-sectional view of a first comparative example not according to the present invention.
  • Figure 2 is a plan view of the first comparative example.
  • Figure 3 is a fragmentary cross-sectional view showing a method of holding plane parallel plates by support members.
  • Figure 4 is a cross-sectional view of a second comparative example not according to the present invention.
  • Figure 5 is a cross-sectional view of an embodiment of the present invention.
  • Figure 6 is a cross-sectional view illustrating an optical device according to the prior art.
  • Figures 1 and 2 are a cross-sectional view and a plan view, respectively, of the essential portions of a first comparative example not according to the present invention.
  • the reference numerals 11 and 11' designate optically transparent plane parallel plates formed of glass or a plastic material
  • the reference numeral 12 denotes cylindrical connection members formed of laminated deformable high molecular film or aluminum foil
  • the reference numeral 13 designates an optically transparent substance such as water, alcohol, silicone oil, deformed silicone oil, silicone gel, silicone rubber or organic oil
  • the reference numerals 14 and 14' denote annular support members comprising, for example, plastic molded articles of high hardness.
  • connection member 12 are thermally secured to each other and have their end portions enveloped so as to form a Y-shaped cross-section.
  • the other ends of the connection members 12 are likewise thermally secured to the support members 14 and 14'.
  • the material of the adhesively secured portions of the connection members 12 may preferably be one which readily permits the connection members 12 to be thermally secured to each other and which will not dissolve into the transparent substance 13 or will not expand, and as such material, mention may be made, for example, of low-density polyethylene or high-density polyethylene.
  • the support members 14, 14' and the connection members 12 are likewise thermally secured together and therefore, the support members 14, 14', like the connection members 12, may preferably be formed of low-density polyethylene or high-density polyethylene.
  • the connection members 12 may be made into three-layer structure having a material such as aluminum foil sandwiched therein in order to prevent humidity absorption.
  • the support members 14 and 14' each may have a material harder than polyethylene, for example, a metal such as aluminum or a plastic such as polycarbonate inserted therein.
  • Figure 3 shows the details of a method of holding the plane parallel plates 11 and 11' by the support members 14 and 14'.
  • the reference numeral 15 designates an adhesive layer for fixing the support member 14 and the plane parallel plate 11 to each other.
  • the support member 14 has a portion 14a protruding from an end of the plane parallel plate 11 and thus, supports the plane parallel plate 11 from the outer side (the side which is in contact with air). This also applies to the support member 14', the plane parallel plate 11' and the adhesive layer 15'.
  • thermoplastic resin or thermosetting resin such as epoxy, polyamide, polyimide, cyanoacrylate, olefin phenol, urethane, silicone resin or halogen-containing resin which is not swollen or eluded by the interval liquid 13 and is excellent in adhesive strength.
  • a rubber adhesive such as NBR (synthetic rubber of a copolymer of butadiene and acrylonitrile), SBR (synthetic rubber provided by the copolymerization of butadiene and styrene), silicone rubber or halogen-containing rubber such as fluorine resin, which can absorb distortion caused by the curing, contraction or the like after adhesion or distortion caused by the physical property differences between the support member 14 and the plane parallel plate 11 such as the difference in coefficient of expansion and the difference in hardness, is preferable as an adhesive.
  • silicone adhesives or modifications thereof, or fluorine adhesives, which are excellent in solvent resistance and weather resistance, are particularly preferable as an adhesive.
  • the plane parallel plate 11 is characterized in that the surface thereof which is in contact with air is held.
  • the outward falling of the plane parallel plate 11 which has heretofore been feared can be prevented.
  • this holding method employed, there is the risk of the plane parallel plate 11 falling inwardly, but since the above-described optical device has the transparent substance 13 enclosed therein, the inward falling of the plane parallel plate 11 is not thinkable unless any extraneous force is applied to the plane parallel plate 11.
  • Figure 4 is a cross-sectional view of the essential portions of a second comparative example not according to the present invention.
  • reference numerals similar to those in the first comparative example designate members similar to those in the first comparative example and therefore, these members need not be described.
  • the reference numeral 16 denotes an adhesive for securing the connection members 12 and plane parallel plates 11 to each other. This adhesive 16, like the adhesive 15, is in contact with the transparent substance 13 and therefore, must preferably not be one which will cause the transparent substrate 13 to degenerate or swell.
  • the adhesive 16 may preferably be an adhesive which will secure the plane parallel plates 11, 11' and connection members 12 to each other with good strength, and may suitably be an adhesive like thermoplastic resin or thermosetting resin such as epoxy, polyamide, polyimide, cyanoacrylate, olefin phenol, urethane, silicone resin or halogen-containing resin, or a rubber adhesive like halogen-containing rubber such as NBR (synthetic rubber of a copolymer of butadiene and acrylonitrile), SBR synthetic rubber provided by the copolymerization of butadiene and styrene), silicone rubber or fluorine rubber.
  • thermoplastic resin or thermosetting resin such as epoxy, polyamide, polyimide, cyanoacrylate, olefin phenol, urethane, silicone resin or halogen-containing resin
  • a rubber adhesive like halogen-containing rubber such as NBR (synthetic rubber of a copolymer of butadiene and acrylonitrile), SBR synthetic rubber provided
  • the plane parallel plates 11 and 11' are held from the surfaces thereof which are in contact with air, by the support members 14, and therefore, not only the outward falling of the plane parallel plates 11 and 11' can be prevented, but also the plane parallel plates 11 and 11' and the connection members 12 are adhesively secured together by the adhesive 16, whereby the adhesive 15 and transparent substance 13 do not contact with each other and thus, the transmission of air can be reduced. That is, there is obtained the effect of enhancing the airtightness of the optical device.
  • Figure 5 is a cross-sectional view of the essential portions of an embodiment of the present invention.
  • reference numerals similar to those in the first and second comparative examples designate members similar to those in the first and second comparative examples and therefore, these members need not be described.
  • the connection members 12 are adhesively secured to the plane parallel plates 11 and 11' by the use of an adhesive 16, and the connection member 12 are thermally secured to the support members 14 and 14'.
  • the plane parallel plates 11, 11' are held from the surfaces thereof which are in contact with air, as in the first embodiment, and therefore, not only the possibility of the plane parallel plates 11, 11' falling outwardly can be prevented, but also the adhesive securement and thermal securement can suppress the transmission of air into the interior of the optical device, and by such structure, the peeling of the connection members 12 can be prevented.
  • the transparent plates when two transparent plates are disposed in opposed relationship with each other and the transparent plates are supported by the support members and the support members and securing members are connected together by the connection members and a transparent substance is enclosed therein to form an optical element such as a variable angle prism, the transparent plates are held from the surfaces thereof which are in contact with air, by the support members, as previously described, whereby there can be achieved an optical device in which the transparent plates can be prevented from coming off the support members.
  • connection members being adhesively secured to the transparent plates, the transmission of air from the surfaces on which the transparent plates and the support members are adhesively secured together becomes unthinkable, and there can be achieved an optical device the airtightness of which can be enhanced.
  • connection members being adhesively secured to the transparent plates and being thermally secured to the support members, there can be achieved an optical device the airtightness of which is more enhanced and in which the peeling of the connection members can be prevented by the dual structure of adhesive securement and thermal securement.
